How the Brain Adapts
With each passing year we learn more about the brain, and in particular, about it’s amazing ability to adapt. And if you are an avid adult reader who was once a dyslexic child, it’s likely that an interesting adaptation has occurred, that being that you are reading while using only one eye, even though you might be completely unaware of it.
Some who once struggled with reading now read with one eye without realizing it.What happens is that the brain, faced with two conflicting, and confusing, outputs from the eyes, due to your poor visual skills, finally decides to deal with the matter itself and selects the output of one eye for processing, while ignoring the output of the other eye. That this actually does occur has been demonstrated repeatedly among once-dyslexic adults, where testing reveals that output from one eye is not being processed, even though that eye is open and is receiving input normally. In fact, if one covers the eye that is being actively used, the output from the other eye will be processed, so an affected individual will naturally assume that both eyes are functioning normally.
Thus, the reason you are reading comfortably as an adult is possibly due to the brain adapting to your deficient binocular vision skills by refusing to process the output of one eye when reading. Should that be the case, your dyslexia is anything but cured, for an adaptation is hardly a cure.
Now, this doesn’t happen to everyone, of course. Some adults read well, but have to take frequent breaks because their visual systems are fatiguing due to poor visual skills. Others read well because their visual skills finally did develop sufficiently that reading became effortless.
In all such cases, however, a genetic tendency is likely to be present and is able to be passed on. In that sense, especially, dyslexia cannot be “cured,” and a dyslexic parent needs to be aware of the likelihood that some of his or her children will probably share the genetic predisposition to dyslexia.
